Product details
Overview
DDZ9715-7 from Diodes Incorporated is a surface-mount low-current Zener diode in SOD123 package, rated for 36 V nominal zener voltage (min 34.2 V, max 37.8 V) at 50 µA test current, with 500 mW power dissipation on FR-4 PCB at TL = +75°C and 0.05 µA maximum reverse leakage at 27.3 V. It serves as a precision voltage reference or overvoltage clamp in portable battery-powered sensor nodes and low-power analog signal conditioning circuits.
For engineers reviewing the DDZ9715-7 datasheet, DDZ9715-7 pinout, DDZ9715-7 application, or DDZ9715-7 equivalent, this device is selected for stable low-bias voltage regulation where thermal stability, low leakage, and SMT compatibility are critical - especially in space-constrained, energy-harvesting, and automotive-grade auxiliary supply monitoring designs.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage tolerance (±5% at 36 V), specified at a low 50 µA test current to minimize self-heating and enable use in microamp-level bias networks. Its temperature coefficient is +0.08 %/°C (typical), optimized for stable reference performance across –65°C to +150°C operating range.
The device features a cathode band marking for polarity identification, matte tin–annealed terminals solderable per MIL-STD-202 Method 208, and meets J-STD-020 moisture sensitivity Level 1. Its SOD123 package delivers 150 °C/W junction-to-lead thermal resistance, supporting reliable operation under pulsed or low-duty-cycle conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-current Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36LT1G | Same 36 V nominal, but ±6% tolerance (vs. ±5%), 200 mW PD, higher 1 µA IR @ 27.3 V | Limited to non-critical references; unsuitable for <1 µA leakage budgets or high-temp automotive use | Select when cost sensitivity outweighs leakage and thermal performance requirements |
| MMSZ4687T1G | 36 V nominal, ±5%, but 500 mW PD only on thermally enhanced pads; 0.1 µA IR @ 27.3 V (2× higher) | Requires larger copper area for thermal management; less suitable for ultra-low-leakage battery monitoring | Prefer for general-purpose industrial boards where layout allows extra thermal relief |
Compared with BZX84-C36LT1G and MMSZ4687T1G, DDZ9715-7 delivers tighter voltage tolerance, lower leakage, and superior thermal resistance in identical SOD123 form factor - making it optimal for battery longevity-critical and high-reliability embedded systems.

FAQ
What is the maximum reverse voltage before breakdown for DDZ9715-7?
The DDZ9715-7 exhibits sharp reverse breakdown at its nominal zener voltage of 36 V, with guaranteed operation between 34.2 V (min) and 37.8 V (max) at 50 µA test current. Below 27.3 V, reverse leakage remains ≤0.05 µA - no defined "maximum non-breakdown voltage" is specified, as Zener behavior is gradual onset above knee voltage.
Can DDZ9715-7 be used in place of a 33 V Zener diode?
No - DDZ9715-7 is specifically rated for 36 V nominal zener voltage and is not interchangeable with 33 V devices like DDZ9714-7. Substituting would shift reference or clamp thresholds by ~9%, potentially causing ADC scaling errors or insufficient overvoltage protection in sensitive circuits.
Is the SOD123 package of DDZ9715-7 compatible with standard reflow profiles?
Yes - the SOD123 package uses matte tin–annealed terminals qualified per MIL-STD-202 Method 208 and is rated for moisture sensitivity Level 1 (unlimited floor life). It supports industry-standard lead-free reflow profiles (peak 260°C, 60 sec max) without preconditioning.
Does DDZ9715-7 require a heatsink for 500 mW operation?
No - the 500 mW rating is validated on standard FR-4 PCB with Diodes' recommended 1-inch² copper pad layout (per DS30410 Fig. 1). No external heatsink is needed; thermal management relies on PCB copper area, and RθJL = 150 °C/W reflects this board-level conduction path.
